在 ASP.NET webforms 前端自动加载新插入的行（SQL Server 数据库）？

Question

I have a SQL Server database with one table and I am doing operations using Entity Framework 6 in C#.

I have a jQuery in my frontend which calls a method in the C# backend and loads the data from the database using Entity Framework.

Now I want to invoke this method automatically as soon my table in database gets any new rows / data.

I don't want to use SignalR, wants to keep it simple as possible.

I am still figuring out the best possible and easiest way to do this. If I add a trigger on my table in SQL Server, then how it will invoke my jQuery method or C# method?

It can't, at least not directly, without implementing something poorly like a CLR procedure that then invokes your application.

You can look into Query Notifications to potentially accomplish your goals in a more vanilla way, but be warned, you'll probably be the only person in existence actively using this feature:

Built upon the Service Broker infrastructure, query notifications allow applications to be notified when data has changed. This feature is particularly useful for applications that provide a cache of information from a database, such as a Web application, and need to be notified when the source data is changed.
